A perfect symbol of the interplay between Rijeka’s industrial heritage and water: together fundamental elements of the city’s identity. Two millstones, complete with their original machinery, which were once used in the city’s first paper mill (see “Industrial Rijeka” ) form the centrepiece, and water streams in intriguing formations over the toothed edges of the gears and cogs. “Let a tool of work become a source of joy” reads the inscription: the paper mill presented the fountain to the city in honour of its many workers on the occasion of the mill's 150th anniversary.
